Abstract
We have performed the thoracic aortic-abdominal aortic bypass and the right renal-right common iliac bypass on a case of middle aortic syndrome, which is an aortostenotic disease involving the bifurcation of the renal arteries and having severe hypertention as the chief symptom. Blood pressure in upper extremities improved well from 170mmHg before operation to 140mmHg thereafter.
In Japan, the present disease has not been regarded as an independent entity, but is often classified as atypical coarctation of the arota, which is subtype of aortitis syndrome. On the contrary, in Europa and the United States, the concept of middle aortic syndrome is becoming general because of its specific clinical symptom due to anatomical specificity although its diverse pathogenesis. The stenotic region of this disease commonly involves the bifurcations of the major aortic branches. The concept of middle aortic syndrome is, therefore, of great value for planning the reconstruction of the vesseles and the therapeautics.
